Tyre pressures at Oulton Park Island
The venue as mapped, to scale. Oulton Park Island is one of 3 layouts sharing this tarmac, and its exact course differs from the full-circuit outline shown. Track outline © OpenStreetMap contributors (ODbL).
How hard a circuit works each corner of the car shows up as tread temperature, and temperature is what sets pressure. GripCalc carries corner heating figures for Oulton Park Island as a starting point: how much hotter each tyre runs over the session's base temperature, from the layout's mix of corners and load. They pre-fill the calculator when you pick the circuit, and your own pyrometer readings refine them from the first session.
| CORNER | RUNS HOTTER BY, °C |
|---|---|
| Left front | +3.5 |
| Right front | +2.5 |
| Left rear | +4.5 |
| Right rear | +3.5 |
ESTIMATED — class-based starting values over an 85°C session base, derived from this layout's type (direction, speed profile, load), and shared with circuits of similar character rather than measured here. Not gospel: enter your own pyrometer figures after a session and they take precedence.
What Oulton Park Island asks of a tyre
The Island layout keeps Oulton's elevation and character but shortcuts the Fosters loop, making the lap busier per mile. The same compressions and kerbs apply with less recovery between them, so tyres run warm and the car needs to take kerbs without pressure spikes unsettling it.
Warm steady-state temperatures from the busy rhythm
Chicane kerbs punish inner shoulders; check inner zones
Crest unloadings then compressions cycle pressures through the lap
A 992 GT3 on Cup 2 R at Oulton Park Island
Published hot target 30.5 / 32.0 psi at 92°C tread, on a 15°C morning, with the corner figures above: cold set 21.3 / 21.4 front, 22.4 / 22.5 rear. A different car, tyre or morning moves every number, which is what the calculator is for.
